Dear List

I am going to be validating a cleaning and sanitation programme and as
part of this will be taking contact slides (press plates) of dirty
surfaces prior to cleaning. The average of the dirty surface counts
(CFU/cm2) should not be greater than the expected (allowed) average APC
count for the product.

I need some help with being able to make a comparison of a CFU/cm2
count and a APC/g count as I am sure there must be some conversion
factor when comparing results from a cm2 to /g.

NOTE: These will be translated into log10 counts first.

Thankyou for your assistance.

Regards,

Stella
